Rails - Jul 2006 - Profiling functional tests

I looked at the basic profiling information in the Agile book and  
around google, but the profiler script that comes with rails doesn''t  
really seem sufficient.

Something like: ruby -r profile <functional test file>

Seems a lot more like what I''m trying to get at.  But is there any  
solution that I missed that will give me nice profiling output for  
functional test suites without cluttering the profiler output with  
framework calls?

Thanks,
Mat
